EGG BEATER AND MIXER.

Application filed March 24, 1922. Serial No. 546,418

To all whom. it may concern:

Be it known that l, ARTHUR V. MINNEY, a citizen of the United States,and a resident of Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and useful Improvements in EggBeaters and Mixers, of which the following is a specification.

The object of the invention is to provide an improvement of thischaracter wherein the agitating or mixing of the substance being handledis carried out in a closed receptacle so as to be entirely clean andhighly sanitary and which is so constructed and organized as tothoroughly beat or mix the ingredients whereby to procure a well beatenor thoroughly mixed product.

Another object is to provide an improve ment of this character whichgreatly facilitates the carrying out of the beating or mixing action andprovides not only for the beating of eggs, coatings, frost-ings,thickenings, cake-doughs or the like but also for the mixing ofmayonnaise, thick chocolates and custards or the like.

Another object is to provide an improved beaten which may be readily setup upon the table, shelf, bench or the like and which may beconveniently taken down and stored when not in use.

Another object is to provide an improve: ment of this character which isof simple and durable construction, reliable in operation and easy andcomparatively inexpensive to manufacture.

Other objects and advantages of the invention reside in certain novelfeatures of construction, combination and arrangement of parts whichwill be hereinafter more fully described and particularly pointed out.in the appended claims, reference being had to the accompanying drawingsforming part of this specification, and in which:

Figure 1 is a detail perspective view of the preferred embodiment of theinvention. certain of the parts being showin disasiscmbled and certainparts being omitted for the sake of illustration;

Figure 2 is a view. partly in vertical section and partly in elevationof the beater or mixer;

Figure 3 is a detail perspective view of the complementary part of thebed or table of the machine.

Referring to the drawings wherein for the sake of illustration is shownthe preferred embodiment of. the invention, the numeral 10 designatesgenerally the frame which includes a horizontal base bar 11 havingintegrally formed therewith at one end an angular bar 12, the horizontalport-ion 12 of which is coplanar with the underlying portion 11 of thebase bar 11. The

underlying portion 11 has threadedly connected thereto a clamping screw13, one end of which is formed to constitute a handle and the other endof which carries a clamping plate 14, the clamping plate 14: and thehorizontal portion 12 of the annular bar 12 being adapted to clamp orgrip the projecting ledge of the table, shelf or the like, indicated atT in Figure 2. The frame 10 also has integrally formed therewith astandard 15 which extends vertically and which is arranged at the end ofthe base bar remote from the clamping screw 13. A skeleton, table or bed16 is provided and preferably is made up of horizontally extending flatportions 17 and 18 and an arcuate or semicircular connecting portion 19to which a complementary and removable portion 20 (see Figure 3) isadapted to be secure'dby means of rivets or other suitable fasteningmeans, these rivets or fastening means operating through openings 20formed in the ends of the brace bar and opening-s17 and 18 formed in thehorizontal portions 17 and 18 of the table. The bed 'fort able 16 isintegrally formed with thestandard "15 and is also supported by means ofa vertical brace bar 21 and an angular brace bar 22 extending from thebase bar 11 and the angular bar 12 respectively as clearly shown in thedrawings. A receptacle or container 25 is supported upon the table 16and is adapted to contain the substance or substances to be beaten ormixed as the case may be. This receptacle 25 is preferably ofcylindrical form and is provided with a cover 26 having a dependingflange 27 spaced slightly inward from its periphery and adapted toengage the inner peripheral wall of the receptacle to completely closethe upper open end of the receptacle when this is desired. A handle 28is fitted to the cover.

Means is provided for releasably securing the receptacle to the frameand preferably comprises a pair of pins 30 welded or otherwise suitablysecured to the base of the receptacle and depending downwardlytherefrom. These pins 30 are adapted to be re ceived in sockets 31provided therefor in the portions 17 and 18 of the bed. The means forsecuring the receptacle to the frame also includes a laterally extendingpin 32 carried by the peripheral wall of the receptacle adjacent theupper end thereof and cooperable with the V-shaped socket or notch 33formed'in the upper end of the standard 15, the pin 32 being also weldedor otherwise suitably secured to the receptacle 25.

The receptacle 25 is provided at its center with a tube or cylindricalcasing 35 which has its lower end suitably secured or formed integralwith the base of the receptacle and which upstands from the base, theupper end of the tube terminating a substantial distance below the upperend of the receptacle, as shown in Figure 2. i'thin the tube orcylindrical casing 35 bearings 36 and 37 are arranged, and in thesebearings an operating 2 shaft 38 is journaled, the operating shaft beingsupported at its lower end in a step or spindle bearing 39 and beingprovided with a thrust bearing in 'the form of acollar 40 secured tothe'shaft by a pin 41 and operating between the portion 12 of theangular-bar 12 and a lateral arm or lug 42 integrally formed with theannular brace bar 22 and extending parallel to the portion 12 of theportion 12.

The upper end of the operating shaft 38 is squared, as at 38 and thissquared portion of the operating shaft fits in a squared opening 45provided inthe hub 45 of the beater or mixer, designated generally at46. The heater or mixer 46 includes angular arms 47 integrally formedwith the hub 45 and carrying a plurality of beater blades or fingers,indicated at 48.

Any desired number of beater blades or fingers may be provided butpreferably they are provided in the number and in the manner shown inthe drawings. The hub 45 of the beater is elongated, as shown in Figure2, and the lower end of this elongated hub rotatably abuts the adjacentface of the bearing 36. The tube 35 has its upper end provided with aninturned flange 35 which snugly engages the periphery of the hub 45although permitting free rotation of the hub with respect thereto. A capor hood 50 is secured to the hub of the beater by suitable fasteningmeans, such as by means of rivets 51 and extends down around but spacedfrom the tube 35 and in this manner displacement of the substance beingbeaten or mixed from the receptacle or interior of thetube is prevented.

Means is provided for rotating the operating shaft so as to actuate theheater, and this means preferably includes a relatively small beveledgear 55 fixed to the operating shaft. as at 56 and meshing with arelatively large beveled gear 57 secured, as at 58 to one end of a jackor countershaft 59 journaled in bearings provided therefor in the frameand rotated from a hand crank 60 by means of a large gear 61 secured, asat 62, to the crank shaft of the hand crank and meshing with a smallgear 63 secured, as at 64 to the jack or countershaft 59. The crankshaft 60 and the jack shaft 59 are mounted in suitable bearings providedin the frame 10 and they are also supported and constrained to theirproper field of actionby means of a bracket 66 having offset bearingportions 67 and 68 provided thereon and secured at its ends by means ofscrews 69. The ,bracket 66 serves not only to rotatably journal theshaft .59 and 60 but it also prevents endwise displacement thereof thusfunctioning as thrust bearings for these shafts. The hand crank $0preferably includes a hand grip or hold 0 The materials or substances tobe beaten or.

mixed may be placed in the receptacle before or after assembling thebeater therewith as desired. After the substances to be mixed or beatenare placed in the receptacleand the beater has been assembled with theoperating shaft'the cover is placed in position, as shown in Figure 2.The hand crank 60 may then be turned to carry out the beating operation.When this hand crank 60 i turned its gear 61 causes the gear 63 torotate and the gear 63 causes the shaft 69 to rotate which in turnrotates the operating shaft 38 through the beveled gears 57 and 55. Therotation of the operating shaft causes the beater to revolve and thebeater fingers thoroughly mix or beat the substances within thecontainer. The gear employed to transmit the rotation of the hand gripto the beater is such as to speed up the beater and so as to enable theoperator to carry out the beating or mixing operation with the leasteffort and with the greatest efficiency.
